Mate In 2 Puzzle (Rated 1199): Spot Mate in 2 — Rook Endgame
This chess endgame puzzle is a classic example of how active rook placement can decide the game immediately. White’s rook dominates the board, restricting the enemy king and creating a mating net around the back rank and nearby escape squares. In classical chess, rook activity often matters more than extra pawns because a single forcing sequence can end the game before material advantages matter. The key idea is to use checks and coordination to trap the king with no safe flight squares.
